LUBRICATOR.

EPECIFICATION forming peirt of Letters Patent No. 298A68, dated May 13,1884.

Application filed February 25, 1884. (No model.)

To all whom zit may concern;

Be it known that we, WILLIAM Horn and JAMES HOMAN, citizens of theUnited States, residing at Springfield, in the county of Clark and Stateof Ohio, have invented a new and useful Lubrioator, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

Our invention relates to lubricating-cups, and more particularly to avalve for the cap or cover of the same; and it has for its object toprovide a valve which will thoroughly and effectively close the openingin the cup,which is used for the introduction of oil or other lubricant,to prevent the entrance of dust or dirt and. other matter within thecup.

The invention consists in the combination, with the cap or cover of anoil-cup provided with a suitable oil-opening, of a hinged valve forclosing said opening.

The invention further consists in the improved construction andcombinations of parts hereinafter fully described, and pointed out inthe claims.

In the drawings, Figure 1 is a detached view in perspective of the capor cover of a lubricating-cup, the view being taken from the under sideof said cap. Fig. 2 is a section on the line or x of Fig. 1. Fig. 3 is atransverse section on the line of Fig. 1, and Fig. 4 is a plan view ofthe front of the cap.

I n the accompanying drawings, in which like letters refer tocorresponding parts in the several figures, Arepresents the cap or coverto the lubricating-cup, which may be of any suitable or preferredconstruction. Upon the under side of this cap or cover are located, at asuitable distance from the opening a of the oil-cup, depending brackets,B. In these brackets B is mounted ashaft, D, upon which is mounted theend of the valve E. This valve E may be of any suitable'construction;but our preferred form is as shown in Fig. 1. In this case the valveconsists of the plate b, having the raised or convex portion 0 and therearwardly-ourved portion 61' extension d, the

end of which isprovided with a perforation, c, and which is mounted uponthe rod or shaft D. Upon this rod or shaft D is mounted a coil-spring,F, the central portion of which is bent outwardly to form a loop, f,which bears against the under side of the valve near its front end, andholds the same in close contact with the oil-opening and thoroughly andeffectivel y closes the same. H represents a rod or shaft mounted in thebrackets B, and which is for the purpose of limiting the backwardmovement of the valve by the loop f striking against said rod or shaft.When the valve is depressed ,it is stopped by the loop striking the rodor shaft.

It will be seen that by the construction above described a reliable andeffective valve is produced, and onethat will keep the opening to thelubricating-cup closed and prevent access thereto of dust or dirt.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is-

l. The combination, with the cap or cover of a lubricating-cup providedwith a suitable oil-opening, of a hinged valve arranged upon the underside thereof, substantially as set forth.-

2. The combination, with the cap or cover of a lubricating-cup providedwith a suitable oil-opening, of a spring-pressed hinged valve arrangedupon the under side of said cap, adapted to close said opening,substantially as set forth.

3. The combination, with a cap or cover of a lubricating-cup providedwith a suitable oilopening, of a hinged valve arranged upon the underside of said cap, the upper surface of which is made convex in form,substantially as set forth. I

4.. The combination, with a cap or cover of a lubricatingcup providedwith-a suitable oilopening, of a hinged valve, the upper surface ofwhich is made convex, and a spring for bolding the same in saidoil-opening, substantially as set forth.

5. The combination, with the cap or cover of a lubricating-cup providedwith a suitable oil-opening, of a hinged spring-pressed valve secured tothe under side of said cap or cover, and made convex in form,substantially as set forth.

6. The combination, with a cap or cover of alubricating-cup providedwitha suitable oilopening located at about the center of said cap, saidopening being concave in form upon its under side, of a hingedspring-pressed valve secured to the under side of said cap or covering,and made convex in form to fit the consaid shaft and formed with a loopto engage cave opening of the said cap, substantially as set forth.

7. The combination, with a cap or cover of a lubricating-cup providedwith a suitable oilopening, of a valve adapted to fit in said opening toclose the same, said Valve being formed with an extension or projectionupon its lower end, and a spring for holding the same in contact withthe under side of the cover, substantially as set forth.

8. The combination, with a cap or cover of a 1ubricating-cup providedwith a suitable oilopening, of a valve hinged at its rear end upon ashaft secured in downwardly projecting brackets, substantially as setforth.

9. The combination, with the cover of a lubricating-cup provided with asuitable oilopening, of a valve pivoted upon a shaft secured inbrackets, and a spring mounted upon the under side of the valve,substantially as and for the purpose set forth.

10. The combination, with the cover of a lubricating-eup provided with asuitable oilopening, of a valve for closing the same, pivoted upon ashaft secured in brackets to the under side of the cover, a coil-springmounted upon said shaft and formed with a loop to bear against the underside of the valve, and arod for limiting the movement of said valve,substantially as set forth.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in presence of two witnesses.
